To all whom it may concern:

Be it known that 1, PAUL ZGRUNDMANN, a

OstramSaXony, Germany, have invented certain new and useful Improvementsin Machines for Distributin Artificial Manure, Lime, or the Like, of aspecification.

This present v ments in machines for distributing artificial manure,limeor the like over a large surface or over separate rows in auniformly thick layer. This uniform distribution is attained ouslydistributed over the ground y means axle of the vehicle.

In the accom anying drawings in figures of reference refer to like partsthroughout the different views.

In said drawin sz-Figure 1 shows a side view of a part of t e vehicle,the distributing mechanism being partly in section. Fig. 2 shows a backview of the vehicle partly in section. Fig. 3 shows a special,construction Fig. 4 shows a of the worm of the hopper. detail view-ofthe discharge hopper or disshows a cross-section tributer. Fig. 5 p vthrough the inlet hopper shown in Fig. 3.

The hopper 1 is closed at the top by a sieve 2 in order to separate themanure from solid bodies as stones or the like, before it enters intothe inlet hopper and into the dis- The manure thus tributing mechanism.sifted enters a horizontal receptacle 3, which incl oses a 'wormorendless screw 4 consisting of two, parts one of which is left-threadedwhile the other one is right-threaded or reverse. 'lhis worm serves forthe purpose of continuously moving the material introduced through thebroad hopper 1 and thereby prevents the same from leading in front ofthe shut-ell slide 5 thereby regulatin the manure onto the owerdistributing worm (i. In the passage between the upper and lower worms Iplace a coneshaped roofed partition 7 so dividing the passage into twoseparate channels which run into a horizontally placed receptacle 9. Thedriving of the worm l is caused by means of a driving wheel ll) arrangedoutside of the receptacle 3 andactualcd by awhecl 31 mounted on the axleof the vehicle and a sprocket the hopper bein continuw ich the followingis r as to always open and close the channel 1111binvention relates tonnprovedischar e heppcr a distrilniter chain. The proportion of the gearwheel depends on the size of the worm used. Be fore the material isuniformly distributed by the partition 7 into the two channels it mustpass a shut-off slide 5 by which the quantity of the manure entering thelower receptacle is regulated, the slide beingso arranged forrnly.

The cone-shaped partition 7 issituated exactly in the center of themachine so that it covers a driving wheel 11 of the worm 6, the worm 4as left-and right-hand threaded. The wheel 11 is actuated by the driw'ngwheel 31 mounted on the axle of the vehicle through sprocket and chaingear. While the upper worm 4 is employed to press the ma )oint I use thelower worm to again spread t e material over the whole surface of thereceptacle 9 and to eflect the uniform distribution of the manure.

The manure is equally fed over the wall 12 V and completely uniformlydistributed over the 'ound. ln'order to prevent an uneven distributionof the manure on the ground in consequence of the diminishing pressurereduced towards the ends of the hollow recep 'tacle 9, I provide theoverflow wall 12 with a specially adjustable overflow bar 1 3 andlocated in such a manner that the-center r part of said overflow wall isgher than its ends. livery 'nne manure is a. ed i ndgust the openingbetween wall and top oi the receptacle thus as to form a narrow slotthrough which the manure passes.

Below the overflow wall 12 i provide a. '17 the length of whidhcorresponds to the two worms. Inside said hopper are single distributingrods or fall which the material has to pass, whereby it insures a stillgreater uniformity of distri butio'n. The machine as hereinbeforedescribed shall only be "used to distribute manure over large surfacesor broadcast.

If the manure is to be distributed in rows 1 remove the rods 18 andreplace the same by single sloping partitions 19, see Fig. 4,which are)laeed apart at certain distances according to the rows. shown in Fig.4, l place two worms below the hopper 1.. The worms one of which isleft-hand threaded, while the other one is right-hand threaded aremounted at right angles to the direction of the movement of the vehicleand interrupters l8,

In order to prevent clogging or other possible impediments of the workcaused b overfilling of the machine I )rovide on the two outer ends ofthe reeeptac e 9 an opening which runs into'an 0 en casing 20, whichreceives the residue of the material. Froni here the material isreturned by a small worm of an endless screw 21 into the lowerdistributing worm receptacle 9. The worm 21 is driven from the shaft ofthe worm 6 by means of bevel or spur wheels 22, 23, 24, 25.

The end plates of the two receptacles 3 and 9' as well as two parallelside-walls of bearings, as they carry e two worms. The attached to owopening on its side, I mounted on said side wall to lower the ends orraise the center of said overflow bar, and a discharge hopper,substantiallyas set forth.
